Overview
MC14553B 3−Digit BCD Counter The MC14553B 3−digit BCD counter consists of 3 negative edge triggered BCD counters that are cascaded synchronously.
A quad latch at the output of each counter permits storage of any given count.
The information is then time division multiplexed, providing one BCD number or digit at a time.
Digit select outputs provide display control.
All outputs are TTL compatible.
An on−chip oscillator provides the low−frequency scanning clock which drives the multiplexer output selector.
This device is used in instrumentation counters, clock displays, digital panel meters, and as a building block for general logic applications.
